On the surface, this is a future sf book about discovering sentient octopuses and trying to communicate with them. But, this is no Children of Ruin or even a Feed Them Silence; it hinges less on plot and characters, and feels more about worldbuilding in service to philosophy.

I quite enjoyed this book, and the strongest part was just how tightly the book's themes and ideas intertwined through the book's different point of views and the worldbuilding. It's a not-so-far future book with sentient octopuses, overfished waters, AI boats that drive themselves in search of profit, drones driven by humans in tanks, and the first android (but one reviled by humanity). It's a book about language and communication, memory and forgetting, what it means to be human and exist in community, and about fear of others.
